| 摘 要： | 以Bi2O3和SiO2为原料,采用机械合金化制备了硅酸铋(Bi12SiO20)的粉体.通过X射线衍射和扫描电子显微镜分析了合成粉体的相结构和形貌,研究了不同球磨时间对产物相组成的影响;并使用红外光谱分析和拉曼散射光谱对球磨得到的样品进行了分析.结果显示表明:球磨8h后出现了Bi12SiO20的晶相结构;随着球磨时间的延长促进了Bi12SiO20的形成,从而提供了一种可以商业化大规模生产Bi12SiO20压电粉体的方法.

| Abstract: | Bismuth silicate(Bi_(12)SiO_(20),BSO) particles were prepared by the Mechanical alloying method using Bi2O3 and SiO2 as the starting materials.The milled BSO were studied by X-ray powder diffraction,scanning electron microscope,infrared and Raman scattering spectroscopy.After 8 hours of milling the formation of BSO was confirmed by X-ray powder diffraction.The infrared and Raman scattering spectroscopy results suggest that the increase of the milling time lead to the formation of nonferroelectric BSO,as seen by X-ray diffraction analysis.This milling process presents the advantage,that melting is not necessary,and the high efficiency of the process,opens a way to produce commercial amount of crystalline piezoelectric powders. |
